MAX11336ATJ+T 概要
A SAR ADC is a successive-approximation-register analog-to-digital converter that uses a binary-search algorithm and an internal capacitive network to convert an analog input into a digital code, one bit per clock cycle. SAR ADCs occupy the middle of the converter hierarchy between flash ADCs (fastest, highest power) and delta-sigma ADCs (slowest, highest resolution). The MAX11336 belongs to the Maxim Integrated SAR ADC product family and is part of a broader category: data converter -> ADC -> SAR ADC -> multi-channel low-power SAR ADC. Compared with delta-sigma converters, SAR parts deliver deterministic latency, which makes them well suited to multiplexed multi-channel data-acquisition loops.
Key features include 500 ksps throughput on a single +3.3 V supply, low power consumption of approximately 5.4 mW at full speed, hardware- or software-configurable analog input ranges, and 16 analog input channels that can be configured for 4-, 8-, or 16-channel single-ended or pseudo-differential operation. The integrated post-mux signal-conditioning access lets designers insert external filters or buffers between the multiplexer output and the ADC input - a feature rarely found in integrated multi-channel SARs.
The MAX11336's CMOS SAR architecture combines an input track-and-hold with an internal reference capacitor DAC and a precision comparator. Its 500 ksps full-linear-bandwidth and external-reference architecture allow the noise floor and absolute accuracy to be tuned by the reference choice. The serial-interface controller supports SPI Mode 0 and Mode 3 with QSPI- and MICROWIRE-compatible timing modes. Power dissipation scales linearly with sample rate because there is no continuous internal conversion loop, simplifying thermal budgeting at lower throughputs.
Typical applications include industrial process control and PLC analog input modules, automotive sensor interfaces (battery management, current shunt monitoring, and HVAC controls), portable and battery-powered instrumentation, optical-module monitoring, and multi-loop data-acquisition systems. The 32-TQFN (5x5) package makes the part attractive for compact PCB layouts with strict height restrictions, such as handheld test equipment and modular IO cards.
When designing with this device, place the reference decoupling capacitor and the input RC network as close as possible to the analog pins, and route the analog and digital grounds as separate nets joined at a single point under the exposed pad. Because the part is specified for the automotive -40 to +125 °C range, derating of input bandwidth and reference settling time at high temperature should be validated against the datasheet AC Electrical Characteristics table.

主な用途
MAX11336ATJ+T の用途: 6 件s: Industrial Process Control and PLC Analog Input Modules, Automotive Sensor Interface (Battery and HVAC), Portable and Battery-Powered Instrumentation, Optical Module Monitoring (SFP/QSFP Transceivers), Multi-Loop Data Acquisition Systems, IoT and Smart Sensor Edge Nodes.
Industrial Process Control and PLC Analog Input Modules
The MAX11336ATJ+T fits industrial process-control analog input modules because its 500 ksps SAR throughput supports simultaneous sampling of multiple 4-20 mA or 0-10 V sensor loops while its 4-/8-/16-channel multiplexer eliminates the need for an external analog mux. The 12-bit (4096-step) resolution is adequate for 0.1% full-scale process-variable readout. Place the part on a dedicated analog island with its exposed pad tied to the analog ground pour; route SPI traces over a continuous digital ground on an inner layer to keep common-mode noise below the 1 LSB threshold.
おすすめ
Automotive Sensor Interface (Battery and HVAC)
The MAX11336ATJ+T is rated for the automotive -40 °C to +125 °C temperature range per the manufacturer datasheet, making it well suited to under-hood battery-management current-shunt monitoring and HVAC actuator feedback. Its 500 ksps SAR core delivers deterministic conversion latency so the BMS microcontroller can synchronize ADC readings with PWM-driven actuator timing. Use the post-mux signal-conditioning access to insert an RC anti-aliasing filter that attenuates inverter-switching noise above the Nyquist band.
おすすめ
Portable and Battery-Powered Instrumentation
The MAX11336ATJ+T consumes approximately 5.4 mW at full 500 ksps from a 3.3 V supply, and its power dissipation scales linearly with sample rate, allowing handheld instruments to throttle throughput and extend battery life. A 12-bit SAR with 16 input channels lets a handheld multimeter or data-logger replace multiple single-channel ADCs with a single 5x5 mm TQFN. Power-down current drops below 1 uA between bursts, which is critical for solar or coin-cell-powered sensors sampling once per minute.
おすすめ
Optical Module Monitoring (SFP/QSFP Transceivers)
The MAX11336ATJ+T's 500 ksps throughput and 12-bit resolution are well matched to SFP/QSFP transponder diagnostic monitoring, where the host controller multiplexes APD bias, laser temperature, supply voltage, and receive power onto a single ADC. The 32-TQFN 5x5 mm package fits easily inside an SFP-style cage footprint. The SPI interface connects directly to the module's microcontroller, and the automotive temperature grade tolerates the elevated ambient inside a 1U/2U switch chassis.
おすすめ
Multi-Loop Data Acquisition Systems
The MAX11336ATJ+T supports 4, 8, or 16 input channels in a single SAR ADC, allowing a single device to replace several discrete ADCs in a multi-loop DAQ system and saving both PCB area and BOM cost. The 12-bit SAR core delivers deterministic latency on every conversion, which simplifies loop synchronization for control applications. Combined with the post-mux signal-conditioning access, designers can implement individual anti-aliasing filters per channel before the ADC input, improving effective ENOB in noisy industrial environments.
おすすめ
IoT and Smart Sensor Edge Nodes
The MAX11336ATJ+T integrates 4-16 analog channels in a 5x5 mm TQFN, which is essential for compact IoT edge nodes that aggregate multiple sensor types (temperature, pressure, humidity, gas) on a single PCB. Its SAR 500 ksps throughput captures fast transients such as MEMS accelerometer outputs or vibration events, and its sub-1 uA power-down current between conversions extends battery life for years in remote sensor installations. The SPI/QSPI/MICROWIRE interface connects directly to low-power Cortex-M0/M4 host microcontrollers used in IoT edge designs.

設計ノート
Estimated: Place the 10 µF reference decoupling capacitor on the REF pin within 3 mm of the pin and use a star ground topology tying the analog and digital ground pours together only under the exposed thermal pad. Route the SPI traces (SCLK, DIN, DOUT, CS) over a continuous ground plane on an inner PCB layer; avoid routing them parallel to the analog input traces for more than 5 mm to keep capacitive coupling below the 12-bit LSB noise floor.
Use the post-mux MUX_OUT pin to insert a differential-mode RC network (typically 100 Ω source impedance and 1 nF X7R capacitor) as an anti-aliasing filter before the ADC track-and-hold. Estimated: with a 500 ksps sample rate and a 100 kHz input bandwidth, the -3 dB corner should be set near 250 kHz to attenuate out-of-band noise by 40 dB before sampling, which preserves the full 5.4 mW power budget and avoids SNR degradation.
Do not leave the AVDD and DVDD pins tied to the same ferrite bead without a local 0.1 µF + 10 µF ceramic bypass on each pin - this can cause digital switching noise to couple into the analog supply and degrade SNR by 3-5 dB. Always issue a hardware RESET pulse on power-up before initiating the SPI communication to clear the channel-configuration register; otherwise the first conversions may use a default channel that does not match the application.
Estimated: At 3.3 V supply and 500 ksps full speed, the part dissipates approximately 5.4 mW (1.6 mA typical) which is well below any thermal concern. At elevated ambient temperatures near 125 °C, however, the leakage of the analog input MUX switches rises, so designers should derate the input bandwidth by ~10% over the industrial temperature range to maintain specified INL/DNL performance.
